Abstract

Un convertisseur ultrasonique comporte des piézo-cellules (1) reliées en séries par des circuits (2) transmetteurs de signaux électriques qui servent de déphaseurs, et un circuit (4) pour régler la pente des ondes acoustiques, dont les sorties sont reliées aux déphaseurs. Un circuit (8) est relié en série à chaque piézo-cellule pour former l'amplitude des signaux sur la piézo-cellule correspondante (1).
